Title: Gas-solid photocatalytic oxidation of environmental pollutants
Inventor: RAUPP GREGORY B
IPC: B01J37/34
Filed: 1990-09-04
Granted: 2002-02-19
Abstract: Means and methods employing gas-solid heterogenous photocatalysis ("GSHP") to counteract the widespread occurrence of groundwater and air polluted by volatile organic compounds (VOCs) such as trichloroethylene (TCE) and non-volatile organic compounds such as polychlorinated biphenyls (PCBs), and the like without creating other environmentally hostile agents. Common treatment methods such as spray tower aeration and activated carbon adsorption, both of which merely convert pollutants into alternate but equally obnoxious forms, can be augmented by the means and methods hereof to create ecologically innocuous byproducts. Heterogeneous photocatalysis allows the complete destruction of those organic water pollutants normally contained in the effluents of existing water treatment facilities. Ambient temperature ultraviolet-illuminated catalyst, such as titanium dioxide, in the presence of moist air, substantially completely destroys trichloroethylene (TCE) type-materials in a gaseous phase.

Title: Picture quality correcting device
Inventor: FUNAYAMA MITUO
IPC: H04N5/911
Filed: 1992-02-07
Granted: 1997-03-18
Abstract: A picture quality correcting device which no longer relies solely on the frequency characteristic for picture quality correction, and which prevents disturbance in the group  delay  characteristic  occurring  due  to  a  large variation in the frequency characteristic of the luminance signal,   thereby  greatly  decreasing  deterioration  of picture  quality  of  the  played-back  image.   A  noise component  from the luminance  signal is  extracted by a noise canceller.   Then, the noise component is deducted from the luminance signal by inverting the polarity of the noise  component  and  composing  it  with  the  luminance signal.   The high-frequency component of  the  luminance signal released by the noise canceller is corrected by a picture-tone circuit.  The amount of noise suppression of the noise canceller and the amount of correction of the high-frequency component of the picture-tone circuit is made variable according to a control voltage by adjusting a  picture  quality  adjuster.    The  amount  of  noise suppression  of  the  noise  canceller  is  adjusted,  for example,  according to a limiting  level  setting voltage generated by an LLC circuit.

Patent CA-2064841-C (CA)
Inventor: YOUNG WISE
IPC: G01N33/84
Filed: 1990-08-13
Granted: 2003-01-07
Abstract: Tissue damage may be quantified, tissue type identified, neural activity monitored or blood hematocrit determined by mea-suring the difference between the total tissue sodium and potassium concentrations in the area in question. Comparison of these measurements with standard values permit evaluation of the amount of tissue damage in cells of the same type or the tissue type in non-necrotic cells. Evaluation over time of normal brain cells permit monitoring of neural activity. By directly and simultane-ously measuring sodium and potassium ion concentrations, for example, a nuclear magnetic resonance spectrometer can image areas of different tissue type in differing colors. In this manner tumors and lesions can be clearly delineated. Measurement of to-tal potassium concentration of a blood sample and the potassium concentration of the cell-free plasma will permit determination of cellular volume fraction (hematocrit).

Title: Bubbling system
Inventor: NAKAGAWA TURUO
IPC: C02F1/24
Filed: 1993-05-10
Granted: 1999-09-21
Abstract: A system for cleaning water in rivers or lakes or for separating oil and water. Stock water to be treated is sucked up by a pressure pump 2 from a portion A to be treated such as a river or lake and is fed to vapor-liquid mixing means 1. This sucked stock liquid is fed with a gas compressed by a compressor 3 so that the compressed gas fed from the compressor is mixed and dissolved by the vapor-liquid mixing means 1 in the stock liquid fed from the pressure pump. After this, the liquid under pressure is reserved in a pressure tank 4 and is fed again to the treated portion A via a feed pipe 6. To the leading end of the feed tube 6, there is attached a pressure valve 5 which is opened at a pressure exceeding a predetermined level, so that it can keep the pressure of the liquid containing the dissolved gas at the predetermined level or more. Thus, a great amount of the very fine bubbles can be produced in the treated liquid of the treated portion d so that flock or oil in the treated portion A can be efficiently lifted by the sticking action of the fine bubbles.      According to this system, the construction can be simplified, and the lifting action by the bubbles can be effected by keeping the pressure of the liquid at a predetermined level or more at all times. Thus, the system can be used anywhere under all circumstances.

Abstract: An in vitro culture system for the perpetuation of an unlimited number of neural progenitor cells. Progenitor cells are iso-lated from particular neural regions and proliferated in suspension cultures in the presence of growth factors. The progenitor cells can be induced to differentiate into neurons and glial cells. The ability to perpetuate fetal progenitor cells allows for produc-tion of a large supply of tissue from a minimal number of fetuses for transplantation into an animal with neurodegeneration. The use of juvenile and adult cells for generating progenitors would eliminate the need to obtain fetal tissue and may allow for patient to supply his own progenitors. Such an approach would eliminate the ethical problem of obtaining fetal neuronal tissue as well as the problem of tissue rejection and the required use of immunosuppressive drugs.
